Sure, I meant AC_PATH_X.  Sorry for the confusion.

I was afraid that the fallback (_AC_PATH_X_DIRECT) is not multilib
aware and might break on 64bit Fedora.
Now I have read the code carefully, and I see I was wrong.
Thanks for correcting me.

On Fedora, both ac_x_includes and ac_x_libraries always end up being
empty, no matter whether xmkmf is available or not.

That is not exactly the reason.  The reason is that "$CC -lX11"
works, without any -L options.  Should that command fail,
_AC_PATH_X_DIRECT would have no chance to find the library directory
because it never tries any path with a lib64 component.

So my version of the statement is:

If -lX11 works without any -I or -L options, then it works out of the
box.   Instalations not using multilib ("lib64 path) also have a high
probability to be handled correctly by _AC_PATH_X_DIRECT.

If any of the recipients of this mail knows about an Xorg user which
does not fit into the above and shall be supported by Autoconf,
please speak up.

Have a nice day,
        Stepan Kasal
